To fulfill the need of the community to take part in the Quercus evolution,
we're starting the Quercus Open Source Modules project.

Goal
The goal is to provide more or less "independent" modules that are not packaged with the main Quercus distribution, but can simply be added by putting the jars in the classpath (e.g. /WEB-INF/lib folder).

Development
Development should take place on GitHub.com/Quercus, as it's by far the most used platform for easy code collaboration.

Contribute a new module
If you want to contribute, please reply to this post, tell something about the module you'd like to start and we'll get everything set-up.

Participate in a module
If you want to participate in a modules development, simply fork the repository on Github, do your work (including tests) and send a pull request.

Existing Modules

Currently, these is the list of available modules (that I'm _aware of_):

In future versions of the testing framework, you will not have to create the resin.conf and the JUnit class, but right now its required.

Building of the module
We're using Maven to build the modules. Please take a look at Quercus-Filter
to see how its done.

Quercus itself as Github-Repository?
It will take some time to properly get Quercus out of our main development repository, as Quercus has grown years with our other products in that environment and we don't simply want to cut it out of that repository and therefor loose all the history and other goodies given by decent SCMs.

We're still very busy with getting our Application Server "Resin" certified and ready for the JavaEE6 Web-Profile, so our resources are currently quite constraint and this will take some time to get done right.

From what I see now, it looks like I have to build my own jar files. Is there going to be any effort to provide those on github?

There will be a repository with pre-build jar files.
As none of the extensions right now available is in a state I would call "final", you'll have to build them yourself right now (but it's quite easy with ant/maven to do so).
